Embodiment Construction

[0041] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0042] refer to figure 1 , shows a system 10 for additively manufacturing a first part 160 in a green state via binder jetting (eg, metal binder jetting). The system 10 includes a first powder bed 100 on a first elevator platform 110 and a powder roller 120 configured to transfer powder from the first powder bed 100 to a second powder bed on a second elevator platform 140 130. An adhesive nozzle 150 (eg, an inkjet printhead) is included and configured to move over the upper surface 132 of the powder bed 130 and deposit liquid adhesive 152 at desired or selected locations. Desired or selected locations of upper surface 132 with powder and binder 152 form a layer of first part 160 (eg, first layer—not labeled). ...

Abstract

The present disclosure provides a method for joining additively manufactured parts. A method of joining parts includes additively manufacturing a first part in a green state. The method includes placing a first part defining at least one receiving feature and forming an assembly with a second part into the at least one receiving feature and sintering the assembly such that a volume shrinkage of the first part secures the second part to the first part. The first part may be adhesive jet additive manufactured, such as metal adhesive jet additive manufactured. Non-limiting examples of the at least one receiving feature include a slot, a T-slot, an L-slot, a keyhole slot, an aperture, a clamp, a flange, and combinations thereof, and non-limiting examples of the second part include a ball stud, a T-head stud, an L-head stud, a bolt, a nut, a flange, and a bracket.

Description

technical field [0001] The present disclosure relates to the joining of additively manufactured parts, and in particular to the joining of binder jetting additively manufactured parts. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Various additive manufacturing techniques or processes are used to manufacture parts, and binder jetting, such as metal binder jetting, is one such additive manufacturing technique with relatively high volume or part yield. Additionally, joining binder jetted parts together or joining prefabricated parts to binder jetted parts using conventional joining techniques such as welding can alter the microstructure and properties of the binder jetted part. [0004] The present disclosure addresses the problem of joining additively manufactured parts, among other problems related to additively manufactured parts. Contents of ...
